from these base stations are typically
thousands of times lower than those
they can get from wireless phones.
Base stations are thus not the subject
of the safety questions discussed in
this document.
3. What kinds of phones are the
subject of this update?
The term 'wireless phone' refers here
to handheld wireless phones with
built-in antennas, often called 'cell' ,
'mobile' , or 'PCS' phones. These types
of wireless phones can expose the
user to measurable radiofrequency
energy (RF) because of the short
distance between the phone and the
user's head. These RF exposures are
limited by FCC safety guidelines that
were developed with the advice of
the FDA and other federal health and
safety agencies. When the phone is
located at greater distances from the
user, the exposure to RF is drastically
lower because a person's RF exposure
decreases rapidly with increasing
distance from the source. The so-
called 'cordless phones, ' which have a
base unit connected to the telephone
wiring in a house, typically operate
at far lower power levels, and thus
produce RF exposures far below the
FCC safety limits.
4. What are the results of the
research done already?
The research done thus far has
produced conflicting results, and
many studies have suffered from
flaws in their research methods.
Animal experiments investigating the
effects of radiofrequency energy (RF)
exposures characteristic of wireless
phones have yielded conflicting
results that often cannot be repeated
in other laboratories. A few animal
studies, however, have suggested that
low levels of RF could accelerate the
development of cancer in laboratory
animals. However, many of the
studies that showed increased tumor
development used animals that
had been genetically engineered or
treated with cancer causing chemicals
so as to be pre-disposed to develop
cancer in the absence of RF exposure.
Other studies exposed the animals to
RF for up to 22 hours per day. These
conditions are not similar to the
conditions under which people use
wireless phones, so we don't know
with certainty what the results of
